String Art: Towards Computational Fabrication of String Images
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper we propose a novel method for the automatic computation and digital fabrication of artistic string images. String art is a technique used by artists for the creation of abstracted images which are composed ... -
A Study of the Effect of Doughnut Chart Parameters on Proportion Estimation Accuracy
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)Pie and doughnut charts nicely convey the part–whole relationship and they have become the most recognizable chart types for representing proportions in business and data statistics. Many experiments have been carried out ... -
Subdivision Schemes With Optimal Bounded Curvature Near Extraordinary Vertices
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present a novel method to construct subdivision stencils near extraordinary vertices with limit surfaces having optimal bounded curvature at extraordinary positions. With the proposed method, subdivision stencils for ... -
Super‐Resolution of Point Set Surfaces Using Local Similarities
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)Three‐dimensional scanners provide a virtual representation of object surfaces at some given precision that depends on many factors such as the object material, the quality of the laser ray or the resolution of the camera. ... -
A Survey of Surface‐Based Illustrative Rendering for Visualization
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper, we survey illustrative rendering techniques for 3D surface models. We first discuss the field of illustrative visualization in general and provide a new definition for this sub‐area of visualization. For the ... -
A Survey on Multimodal Medical Data Visualization
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)Multi‐modal data of the complex human anatomy contain a wealth of information. To visualize and explore such data, techniques for emphasizing important structures and controlling visibility are essential. Such fused overview ... -
A Temporally Adaptive Material Point Method with Regional Time Stepping
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Spatially and temporally adaptive algorithms can substantially improve the computational efficiency of many numerical schemes in computational mechanics and physics-based animation. Recently, a crucial need for temporal ... -
Temporally Consistent Motion Segmentation From RGB‐D Video
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)Temporally consistent motion segmentation from RGB‐D videos is challenging because of the limitations of current RGB‐D sensors. We formulate segmentation as a motion assignment problem, where a motion is a sequence of rigid ... -
Terrain Super-resolution through Aerial Imagery and Fully Convolutional Networks
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Despite recent advances in surveying techniques, publicly available Digital Elevation Models (DEMs) of terrains are lowresolution except for selected places on Earth. In this paper we present a new method to turn low-resolution ... -
Thin Structures in Image Based Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We propose a novel method to handle thin structures in Image-Based Rendering (IBR), and specifically structures supported by simple geometric shapes such as planes, cylinders, etc. These structures, e.g. railings, fences, ... -
ThreadReconstructor: Modeling Reply-Chains to Untangle Conversational Text through Visual Analytics
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present ThreadReconstructor, a visual analytics approach for detecting and analyzing the implicit conversational structure of discussions, e.g., in political debates and forums. Our work is motivated by the need to ... -
Time Lattice: A Data Structure for the Interactive Visual Analysis of Large Time Series
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Advances in technology coupled with the availability of low-cost sensors have resulted in the continuous generation of large time series from several sources. In order to visually explore and compare these time series at ... -
Time-Domain Parallelization for Accelerating Cloth Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Cloth simulations, widely used in computer animation and apparel design, can be computationally expensive for real-time applications. Some parallelization techniques have been proposed for visual simulation of cloth using ... -
Topological Function Optimization for Continuous Shape Matching
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present a novel approach for optimizing real-valued functions based on a wide range of topological criteria. In particular, we show how to modify a given function in order to remove topological noise and to exhibit ... -
Towards Easy Comparison of Local Businesses Using Online Reviews
(The Eurographics Association and John Wiley & Sons Ltd., 2018)With the rapid development of e-commerce, there is an increasing number of online review websites, such as Yelp, to help customers make better purchase decisions. Viewing online reviews, including the rating score and text ... -
Towards User-Centered Active Learning Algorithms
(The Eurographics Association and John Wiley & Sons Ltd., 2018)The labeling of data sets is a time-consuming task, which is, however, an important prerequisite for machine learning and visual analytics. Visual-interactive labeling (VIAL) provides users an active role in the process ... -
